Remus Lupin slowly climbed the stairs inside number twelve, Grimmauld Place. He reached the door he sought, but hesitated outside. He'd never entered Sirius' room before; Sirius' friends had never been welcome here when they were in school, and Remus hadn't wanted to intrude on Sirius' privacy since the Order re-formed. Remus took a deep breath and eased the door open, smiling as he saw the red and gold of the Gryffindor banners, rolling his eyes at the posters of the Muggle girls. Only Sirius, he thought to himself.
A flicker of movement on the wall caught his eye, and he moved further into the room, lighting his wand to see his way better. His chest ached as he recognized a young version of himself, surrounded by those who had once been his closest friends. He felt a lump in this throat as he realized they were each lost to him. James, dead since that fateful night nearly 15 years before; Peter, slave of Voldemort, was dead to him; and Sirius, whom, just an hour before, he'd watched pass through the veil. At this last thought, his rigid control on his emotions broke, and he sat down and wept. He wept for his friends, and he wept for himself. He knew himself to be truly alone now.
The sound of a creaking floorboard outside the room caused him to jump up. Seeing Nymphadora Tonks standing in the doorway, he quickly turned away and surreptitiously wiped his face with the sleeve of his robes. She'd changed her hair from its usual shocking pink, to her natural shade of light brown that now brushed her shoulders.
Tonks crossed the room and placed a hand on Remus' arm, but he flinched away at the touch. She pulled her hand away and stepped back. Feeling guilty for his reaction, Remus looked down into her face, and saw that it was full of hurt, grief, and guilt. He could see the paths that tears had left down her face, and he felt his own tears flow again. He sat down on the bed again, and sobbed into his hands, no longer caring what Tonks thought of him.
Remus felt Tonks sit next to him on the bed. "I'm sorry, Remus," she said. "It's my fault he'd dead."
Remus jerked his head up at these words and looked at her, confused.
"I was dueling Bellatrix," Tonks continued. "I should've been able to handle her myself. If I'd been stronger, better, Sirius would still be alive."
Tears were streaming down Tonks' cheeks, and she couldn't bring herself to look Remus in the eyes. Remus tipped her chin up, forcing her to look at him.
"It's no one's fault. Sirius knew the risks of fighting in this war. He wasn't afraid of death, and he died an honorable death, fighting for what he believed in, fighting to protect those he loved."
Tonks nodded and sniffled a little. Remus slipped an arm around her shoulders, and they sat in silence for a several minutes, each lost in their own thoughts. Remus felt slightly awkward, holding this petite woman who he knew to be so fierce. While they'd been friendly through the Order, Remus realized that they had never actually been alone together before. He'd thought about her from time to time, admiring her fierce loyalty and bravery, he enjoyed her wry sense of humor. She was a beautiful young woman. Young woman, he reminded himself. Much too young for you. She'd never see you that way. After all, who could love a werewolf?
Remus shook his head, trying to clear away these thoughts. It only reminded him of how truly alone he was.
"Alone," he muttered to himself without realizing until the word was out of his mouth.
"You're not alone," replied Tonks, looking up at him again.
"Oh, really?" Remus snapped bitterly. "I have no one. My friends are all dead, or dead to me, at least. I have no family. I'm completely alone."
"You still have Harry. I can see how much you care for him, and how much he cares for you. I think it's clear that he considers you family. And besides that, you have me." She finished with a new tone in her voice, almost a question, full of hope.
Remus looked at her again. "Yes," he said awkwardly, "you- you're a good friend, Tonks."
"I don't want to be just your friend, Remus," she whispered, as she leaned in and brushed her lips against his.
Remus stood up in shock, and he searched for a way to control the situation. "This is wrong."
"What's wrong about two people finding comfort in each other? I've felt more than just friendly for you for quite some time, Remus. I'm not a child; I know what you are, and it doesn't scare me," Tonks said defiantly, standing up and placing her hands on her hips.
Remus knew that he should leave, or tell her all the reasons they couldn't be together – their age difference, the war, and most importantly, his condition. But the emotions of the night were too much for him. His heart, and certain other body parts, won out over his logical head. Remus growled softly as he pulled Tonks against him, crushing his lips against hers. She responded immediately, throwing her arms around his neck, parting her lips to deepen their kiss. Remus slipped his tongue between Tonks' sweet lips, and felt his dick harden as their tongues touched. He could feel Tonks' pert little breasts pressed against his chest. Suddenly, his hands were everywhere, sliding under the t-shirt she wore, up her smooth back, down over her firm ass, squeezing it through her jeans. Tonks unfastened the clasp of Remus' robes and tossed them aside, then pulled his jumper up over his head. She gazed at his scar-covered chest and reached up to run her fingers over the worst of the scars, a long, still-pink scar that reached from his right shoulder, down to his left hip. Remus hissed at her touch, and snatched her hand away. Tonks, however, would not be deterred. She pressed her lips to the top of the scar, then covered it with licks and kisses, all the way down to his hip. Remus groaned at the sensation, and the sight of her, on her knees, her face inches from his cock.
Tonks seemed to realize this at the same time, as she reached up to undo his belt and unfasten his trousers. She smiled up at him as she pushed his trousers down his legs, allowing him to kick off his shoes, and step out of his pants. Remus stood before her in only his boxers, which were tented in front, thanks to his large erection pressing against them. Tonks reached up once more to pull his boxers off, and she gasped when she saw his cock at last. After shoving his boxers down, she gave Remus a little push and he fell back onto the bed. She crawled over to him and took his thick, long cock in her small hands. Remus nearly came out of his skin when she lowered her head and engulfed the tip of his cock in her hot little mouth.
Remus ran his hands through Tonks' hair, pulling it away from her face as he watched her bob up and down on his hard dick. He could not believe this hot little woman wanted him so badly. He groaned loudly as she stroked him with her hand and dropped her mouth down to lick and gently suck his balls. It had been so long, Remus knew he wouldn't last much longer. He sighed as Tonks brought her mouth back to his cock, licking and sucking the whole way up. He lost his control of himself when she swiftly swallowed him in one movement, her lips wrapped around the base of his cock. He threw his head back and cried out as his cum shot out of his cock, straight down Tonks' throat. Tonks pulled back a bit after the first shot, and held the head of his dick in her mouth as she stroked his cock and gently squeezed his balls, milking his cum out and into her mouth.
Remus was gasping for breath as he watched Tonks release his cock, and wipe a drop of cum that had escaped her mouth with her finger, then lick it clean.
"Nymphadora," he said in a hoarse voice. Tonks glared at him for using her given name that she hated so. Remus pulled her to him, and kissed her sweet lips once, before starting to strip her clothes from her lithe body. He pulled her shirt off over her head, and gazed at her perky little tits, nipples hard and pointing at him. Pulling her to stand between his legs, and leaned in and flicked the tip of his tongue over one of her nipples. Her breath came out in a hiss, so he licked it again, more firmly, then wrapped his lips around it and sucked as much of her breast into his mouth as he could.
"Oh! Remus!" Tonks gasped, arching her back and clinging to his muscular shoulders for balance.
As Remus teased her nipples with his mouth, his hands drifted to the waist of her jeans. He unbuttoned and unzipped them, and pushed them down over her hips and she kicked them off along with her shoes. She pulled off her panties and stood before Remus, completely naked. Remus' breath caught in his throat as he gazed at her slender body. He smoothed one hand over her belly to cup her bare pussy, teasing her entrance with one finger. Tonks humped slightly against his hand and he smiled a wolfish grin, thrilled by her response. He slid one finger inside her, savoring the feel of her velvety-smooth pussy gripping him.
He pulled away, and Tonks pouted in disappointment, until he stood up and lifted her onto the bed. He came over her and kissed her, starting at her lips and moving down her body. He paused to lick her nipples once more, then moved over her belly, before he settled himself between her legs. He lifted her legs over his shoulders and teased her by licking all around her pussy, but not where she wanted him most.
"Please, Remus," Tonks moaned, after several minutes of this torture. She bucked her hips at him, hoping to rub her pussy against anything. Remus pulled away, and blew cool air onto her, causing her hips to buck even more wildly. "Please! I need you to touch me, lick me, anything!"
"Mmm," he murmured, "I love hearing you beg."
But he took mercy on her, and parted her pussy lips with his fingers and rubbed his tongue over her clit. "Yesss," she hissed.
As much as Remus had enjoyed teasing her, her scent, and the brief taste he'd just had made him unable to contain himself. He dove into her pussy with gusto, flicking her clit with his tongue, then stiffening his tongue and plunging it into her tight cunt. As she moaned and grabbed his hair to pull him closer, he slid one finger, then a second, then a third into her dripping pussy. He brought his lips up to her clit and sucked it into his mouth, massaging it with his tongue.
"Fuck! Oh fuck yes!" she cried.
Her thighs squeezed his head as her body exploded in the most intense orgasm she'd ever experienced. Remus continued plunging his fingers in and out of her clenching pussy as her whole body quivered in pleasure. He slowed the pace of his hand as her body stilled. He rose up onto his knees and wiped her pussy juice from his face with his free hand, grinning down at her while she recovered. He loved the tremors he felt still pulsing through her pussy.
After a few more moments, Tonks wrapped her hand around his cock which had become rock hard again. She stroked him gently, but looked slightly concerned as she stared at his long and very thick cock in her small hand. Remus pushed her hand away and removed his fingers from her incredibly tight pussy. He came over her and rubbed his cock against her pussy, sliding between her lips, rubbing her clit.
"You're so big," she whispered, in awe of what he'd done to her already, and what that cock could still do to her.
"I'll be gentle," he promised.
Remus guided his cock down to the entrance of her hot little cunt. Tonks nodded, and he slowly eased himself inside her. She gasped as he stretched and filled her. Remus groaned as he bottomed out, fully inside her. He'd never felt a pussy so tight and hot around his cock. He leaned down to kiss Tonks as he slowly moved inside her. After a few minutes of slow, gentle fucking, Tonks grew impatient. She'd adjusted to his size, now she wanted to be fucked hard.
"Maybe a little less gentle," she whispered against his lips.
Remus felt his cock throb at those words; holding himself back had taken all his willpower, now he released his hold on his inner wolf.
"Turn over," he growled, as he pulled out of her pussy.
Tonks scrambled to obey, and once on her hands and knees, she arched her back to give Remus the best possible view of her firm ass. Remus caressed her ass, then guided his cock to her entrance once more.
"Are you sure you want this?" he asked her, thrusting in slightly.
Tonks bit her lip. "Fuck me, Remus. Fuck me as hard as you can. Make me scream," she said huskily.
At that, Remus thrust into her all at once. Tonks cried out in pleasure. He quickly found a steady rhythm of pulling out and slamming back into her, spurred on by her cries and moans. Needing to feel her cunt contract around his dick the way it had around his fingers, he reached around and rubbed her clit with one hand, while pinching and rolling her nipple with the other.
Tonks' cries of pleasure were incoherent and increased in volume the harder and faster Remus pounded into her. She cried out his name causing him to completely lose control of himself. He bit into her shoulder, almost breaking the skin. The shock of that pain on top of all the pleasure sent Tonks into a mind-blowing orgasm. She screamed as her body dissolved into spasms of pleasure, her already tight pussy gripping Remus' huge cock. When Remus heard her scream and felt her pussy tighten around him, he thrust into her one last time and came with a yell that was almost a howl. He collapsed on top of her, and could still feel her pussy contracting on his dick.
Remus rolled to one side, not wanting to crush Tonks underneath him. Tonks lay next to him on her stomach, gasping for breath. Remus rubbed his hands across his face. He'd just had the best sex of his life, but he'd lost control. What if he had broken her skin when he bit her? Would there be contamination if he had? How could he ever forgive himself if he hurt his Dora? His lips curled up slightly at the thought of that name he'd never uttered for her, but he pushed the thought away. She wasn't his, and she couldn't be, if that's the reaction she caused in him. He could never lose control like that again.
He turned to apologize to her, but she'd fallen asleep, a sweet smile of contentment across her face. Perhaps it was better this way, he thought to himself. He'd leave her a note, and she wouldn't be able to wear down his resolve. He got up, pulled on his clothes, scribbled out a letter to her and left it on the pillow. He paused at the door to look back at her, then, blinking back tears, hurried down the stairs and out into the night.
